"1. Google reserves the right to automatically update and install Chrome.

This is becoming standard fare with much software these days, but worth noting.

"The software which you use may automatically download and install updates from time to time from Google. These updates are designed to improve, enhance and further develop the services and may take the form of bug fixes, enhanced functions, new software modules and completely new versions. You agree to receive such updates (and permit Google to deliver these to you) as part of your use of the services."

2. Although you retain any copyrights to content you own and use in the browser, Google says it has a right to display some of your content, in conjunction with promoting its services. Here's there exact wording.

"By submitting, posting or displaying the content you give Google a perpetual, irrevocable, worldwide, royalty-free, and non-exclusive license to reproduce, adapt, modify, translate, publish, publicly perform, publicly display and distribute any content which you submit, post or display on or through, the services. This license is for the sole purpose of enabling Google to display, distribute and promote the services and may be revoked for certain services as defined in the additional terms of those services."

3. Don't be surprised to see more ads.

Traditionally, it is Web pages and not the browser itself that serves ads. Google isn't saying it will change this paradigm, but it's terms of service don't rule that out either.

"Some of the services are supported by advertising revenue and may display advertisements and promotions. These advertisements may be targeted to the content of information stored on the services, queries made through the services or other information.

The manner, mode and extent of advertising by Google on the services are subject to change without specific notice to you."

Also worth paying attention to are the settings when you install it. By default, Chrome will add all manner of shortcuts, so if you don't want it to do that, be sure to click "customize these settings." Of note, it does not make itself the default browser without a user agreeing to do so."
